Background: The Covid pandemic and its aftermath have triggered new alarm and social unrest across the Global South over the deepening international debt crisis that now threatens to derail Universal Health Coverage (UHC), other Sustainable Development Goals (SDGs), future pandemic preparedness, and global warming mitigation. The recent Globalization and Health article by Alex Kentikelenis and Thomas Stubbs (May 2024), "Social protection and the International Monetary Fund: promise versus performance", offers a meticulously quantified rendering of the social costs imposed by the crisis and takes aim at IMF solutions. They advocate for a rejection of IMF austerity programs and offer a valuable prescription for change through the International Labor Organization's "Universal Social Protection" concept.

Surgery remains the primary treatment modality in the management of early-stage invasive breast cancer. Artificial intelligence (AI)-powered visualization platforms offer the compelling potential to aid surgeons in evaluating the tumor's location and morphology within the breast and accordingly optimize their surgical approach. We sought to validate an AI platform that employs dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to render three-dimensional (3D) representations of the tumor and 5 additional chest tissues, offering clear visualizations as well as functionalities for quantifying tumor morphology, tumor-to-landmark structure distances, excision volumes, and approximate surgical margins.

Objective: This retrospective multicenter study aimed to evaluate surgical versus conservative treatment in patients with hypopharyngeal and laryngeal cancer under real world conditions.

Methods: This study included 2307 patients diagnosed with hypopharyngeal or laryngeal squamous cell carcinoma (SCC) in five German tertiary head and neck centers between 01/2004 and 12/2014. Overall, 783 patients with advanced SCC consecutively underwent laryng(opharyng)ectomy (L(P)E).

Nuclear spin isomers of molecules play a pivotal role in our understanding of quantum mechanics and can have significant implications for various fields. In this work, we report the isolation and characterization of stable nuclear spin isomers as well as conformational isomers of a reactive compound, namely carbonyl diisothiocyanate. It can exist as three rotational conformers, two of which, the - and -, were observed in a pulsed supersonic jet by chirped pulse Fourier transform microwave spectroscopy in the 2-12 GHz frequency region.

Understanding the association between initial experimentation with a tobacco product and subsequent patterns of tobacco use among youth is important to informing prevention activities for youth in the US. We conducted an online survey from August to October 2017 among youth aged 13-18 years. The current analysis focused on respondents reporting initial experimentation with any tobacco product (n = 2,022).
